Airport Obstruction Issues
GAA Workshop

Approach Surfaces and Obstruction Removal
• 3 categories of approach surfaces for GA Airports.
– State Licensing
– Part 77
– TERPs Visual Surface (20:1)
New GDOT Airport Licensing Approach Standards
• New State Licensing
– 3 configurations - based on runway length
• < 4,000’
• 4,000’ – 4,999’
• 5,000’ +
– Meets visual approach criteria from design guide
• Surface starts at threshold
• Surface should be clear to meet the minimum state licensing criteria
• Generally least restrictive of the three surfaces
• Airports inspected biennially

New GDOT Airport Licensing Approach Standards
• Obstruction Removal
– obstructions should be removed immediately or removal efforts
should be initiated as soon as possible with written plan provided to
GDOT by specified date in letter.
– if removal is not possible, displace threshold
• Documentation of obstructions: biennial inspection letter
• Notification
– Alan Hood, Airport Safety Data Program Manager and
– GDOT Project Manager
Part 77 Approach Standards
• Generally most restrictive, used as screening criteria
• 6 configurations:
Based on runway category and type of approach
<12,500lb + visual = A(V)
<12,500lb + non-precision = A(NP)
>12,500lb + visual = B(V)
>12,500lb + non-precision @ > ¾ mi visibility = C
>12,500lb + non-precision @ < ¾ mi visibility = D
>12,500lb + precision = PIR
• Surface starts 200’ from threshold
• Surface should be clear to meet FAA 5010 Safety Data Inspection Program
criteria
• Airports inspected biennially

Part 77 Approach Standards
• Obstruction Removal
– Obstructions should be removed or provide schedule for removal
• Documentation of obstructions:
• biennial inspection letter
• FAA 5010 report
• Notification Required
– Provide sketch and coordinates of cleared area
– Alan Hood, Airport Safety Data Program Manager and
– GDOT Project Manager
– GDOT will coordinate with FAA to remove from FAA database
FAA Straight-In TERPs Visual Surface Standards (20:1)
• Surface starts 200’ from threshold
• 20:1 Approach Slope
• Obstructions should be mitigated to maintain night minimums
• When are procedures reviewed?
– Any request for change in approach, name change, LOC-ID change,
runway numeral change, etc
– FAA performs review of airport’s terminal procedures every 2 years

FAA Straight-In TERPs Visual Surface Standards (20:1)
• Obstruction Removal
– mitigate obstructions by:
• removal
• lighting
• PAPI waiver – requires FAA Flight Standards approval
– obstructions should be mitigated to maintain nighttime procedures
and coordinated per new guidelines if given notice after Jan 6, 2014.
• Obstruction removal previous to notice from Flight Procedures.
– Sketch and coordinates of cleared area
– Alan Hood, Airport Safety Data Program Manager and
– GDOT Project Manager
– GDOT notifies FAA to update database
FAA Straight-In TERPs Visual Surface Standards (20:1)
• If Notified by Flight Procedures of 20:1 Obstructions (After Jan 6, 2014):
Who is Responsible?
•Ultimately the Sponsor
- State Licensing and Part 77 Inspections: When obstructions are
identified in an inspection, they become a liability.
- State Licensing surface obstructions could lead to denial of license.
Who is Responsible?
•Ultimately the Sponsor
- Sponsors are also responsible for ensuring the TERPs Visual Surface is
clear. Flight Procedures uses the FAA surveyed obstruction database
to review procedures.
- Obstructions do not automatically disappear from database with
a new survey.
- Must submit sketch with coordinates and boundaries of cleared
areas to get obstructions removed from database.
***If you have been notified you have obstructions by Flight
Procedures – then you validate the obstructions in writing. No
survey or coordinates and boundaries required.
